I you also try to write properly not in sms code then it will be much easier to help and understand, so far i don't get what you are trying to say.

On battery charging just use it, don't turn you N900 off or anything.

And a note on the capacity, it will not have more capacity after a few charges, this i can confirm after testing 20+ battery's for the N900, and god knows how many for other things.
